Can some explain the "hz" parameter?

BlitzMax Forums/BlitzMax Beginners Area/Can some explain the "hz" parameter?

"The operating system doesn't decide what display frequencies are available. It's reported by the drivers." Yes, yes..ofcourse. Sorry.

Good question and which is the reason I prefer to let the driver set the hz value for me. Years ago I read stories where this could cause physical harm, but I've yet to read anything that proves it.
